Earlier post from this morning
After a Tuesday evening round of strong to severe thunderstorms across Central Virginia, the chance for more severe weather and possible flash flooding exists during the afternoon and evening hours Wednesday. A Flash Flood Watch has already been posted from 12 noon until the late evening hours Wednesday.

The Storm Prediction Center has placed Nelson County and much of Central Virginia in the slight risk area for severe weather later in the Wednesday.

The Storm Prediction Center in Oklahoma has also placed Nelson and the surrounding area in the slight risk area for severe weather later in the day Wednesday. Afternoon heating, and plenty of moisture will provide a scenario where severe thunderstorms could develop later today.

Though not a sure bet, the potential for severe weather is better today than the average late Spring day across Central Virginia.
